Abstract

A water jet processing machine comprising a workpiece holding means (3), a nozzle (522) for spurting a water jet to a workpiece held by the workpiece holding means, and a processing water supply means for supplying processing water containing abrasive grains to the nozzle, wherein the processing water supply means (6) comprises a high-pressure water generating means (62) and a processing water delivery means (64) for delivering processing water to the nozzle (522) by high-pressure water from the high-pressure water generating means (62). The processing water delivery means (64) comprises a cylinder (64a) and a partition member (644a) which partitions the inside of the cylinder (64a) into a first chamber (642a) and a second chamber (643a) and can be moved by the pressures of the both chambers, the first chamber (642a) being communicated with the high-pressure water generating means (62) and with a draining (67) means for properly discharging high-pressure water from the first chamber (642a) and the second chamber (643a) being communicated with a processing water storage means (631) for storing processing water and being communicated with the nozzle (522).
